The rear portion 'of In order to makethefeed of the strip 26 the frame is covered by alid12which propositive, it is necessary to provide suitable jects downwardly at its rear to cover-the rear gearing which forces thestrip 26 to travel end of the frame as well as the top portion with the strip 19. This gearing, which is enthereof. The lid 12 is hinged at 13 to the cased within ahousing inside of the frame, is frame. The forward end 14 of the lid 12 best shown in Figure 3. It consists ofadrivprojects downwardly into the frame, being ing gear 30 which is secured to the shaft of immediately in the rear of a deflector 15 the roller 21. The'turning 0f the knob 25 will thus cause the turning of the gear 30. Also secured to the shaftof the spool 21 is a pivoted lever 31 which carries an idle gear 32 meshing with the gear 30. The lever 31 is at the left-hand side of the frame and it is provided with a handle .33 which may be depressed or elevated by pressing down with the thumb or by lifting up. Since the axis of the gear 32 is concentric at all times with the axis of the gear 30, these two gears w1ll always be in mesh regardless of the position of the han- 33 will force the idle gear 32 outof mesh with the idle gear .34. The gear is secured to the shaft of the roller 28 while the gear 36 is secured to the shaft of the roller 29. When the

gears

32 and 34 are in mesh, the

rollers

28 and 29 will be rotated in opposite directions to force the strip 26 .throughbetween them. In order to faeilitatethe engagement of the

rollers

28 and 29 with the strip of paper, the spindles or shafts of therollers 29 are pro- Vided with spring pressed bearing blocks 37 which hold the two rollers in tight-contact and the roller 28 is provided with a knurled or roughened surface at 38. I The strip 26 will thus be held tightly between the two

rollers

23 and 29 and it must pass through between them as through the rollers of a wringer.

In use, the original copy is made onthat portion of the surface shown at 39 in Figure 1. Since the under surface of the strip of paper has a recording coating, a record copy will be produced on the surface of the'strip 19 immediately below the portion 39. The knob 25 is then turned to wind the strip 19 on the spool 21. The turning of the knob 25 sets in motion the gear train shown in Figure 3 and forces the free end portion of the strip 26 to pass through between the

rollers

28 and 29 to be fed outwardly from the machine. At this point the end portion of the strip 26 containing the memoranda or bill is. torn *o{f,.the shield 16 being provided with a cutting edge 'to facilitate the tearing 'of the strip 26.

One of the chief drawbacks ofmachines of this general class is that it is impossible to consult the record without greatinconven ience such as removing the spool containing the record. In the present instance this difficulty is avoided by making all of the parts conveniently accessible for consulting the record. When the lid 12 is thrown back on the hinge 13 it exposes a largeportion of the surface of the record copy, most of the surface between the spool 21 and idle roller 22 being visible. The spindle of the spool 20 is provided with a knob whereby the strip done, however, the handle 33 should first be 7 depressed inorder to throw the idle gears 34:,

35 and 36 out of mesh". The turning of the knob 40 will then turn the two

rollers

28 and 29; These rollers, however, are so constructed that they will firmly hold the strip 26 against movement while the strip19 is moving. For consulting the record it is only necessary to lift the lid 12, to depress the handle 33 and to unwind the strip 19 by turning the knob 40 until the desired record is in the line of vision. Inorder to bring the strip 19 back into position where the next record is to be made it is only necessary to turn'the knob 25 andto thusrewind the strip 19 on to-the spool 21 to the desired position.

Certain features also make the machinefool proof. In making .originaland record copies it is necessary only to turn the knob 25 with the gearing in the position shown in Figure 3. If, however, the knob 40 were accidentally or carelessly turned while the idler is in mesh, it might causean unwinding of the strip 19 such as to result in thetearing or tangling of the strip. The turning of the knob 40 would produce a tension on the strip 19 in the direction opposite the winding, direction. Due to thearrangement oft-he gears 30 and 32 a movement of the gear 30in the reverse direction will almost instantly force the gear. 32 out of mesh with the gear-.34...

Having thus described my invention in such full, clear and exact terms that its'construction and operation will be readily understood byv others skilled in the art to which it pertains, what I claim as new and desire to secure by Letters Patent of the United States is:
